Dictate slowly and distinctly the problems. After each is read, wait a moment so that the children may all have time to solve the problem, then give the signal, "Write," whereupon the entire class write their answers. At the close of the exercise, have the pupils exchange papers and then, as the teacher or one of the pupils reads the correct answers, have each answer marked C (Correct) or X (Wrong). Then have the papers returned to their owners and ask the pupils who failed on the first problem to stand. Find out their difficulties and give them the necessary help. In the same way, help the pupils who failed on the econd problem, and then those who failed on each of the other problems. Short tests of this kind may very profitably be given two or three times a week. When carefully planned, the time required for a test containing five problems need not be more than ten minutes. |
